3. Installation Instructions
3.1 Pre-Installation
- Ensure the air supply is pristine, devoid of moisture, and oil-free.
- Validate that the valve model perfectly aligns with the machine's pneumatic interfaces.
3.2 Installation Procedure
1. Mounting: Securely affix the valve in a vertical stance at the designated spot on the press pneumatic control panel using robust M6 bolts.
2. Pneumatic Connections:
- Main Circuit: Direct the air supply to the inlet (P) and link the actuator (e.g., cylinder) to the outlet (A).
- Redundant Circuit: Seamlessly connect the backup channel independently to prevent cross-interference.
3. Electrical Wiring:
- Solenoid Coil Voltage options: DC24V±10% or 110V/220V (ensure specification in advance) (Red: +, Black: -).
- Firmly secure the grounding wire to the equipment's earthing terminal.
4. Operating Procedures
4.1 Pre-Operation Checks
- Assure the manual reset button is switched to the "ON" position.
- Engage test button to simulate an emergency stop and verify dual-channel synchronization.
4.2 Normal Operation
- During operation, both valves operate concurrently. The failure of any channel illuminates a red alarm light and triggers automatic backup activation.
4.3 Emergency Stop
- Activate the E-stop button to cut off the air supply synchronously, immediately halting the press slide.

5. Maintenance
5.1 Routine Maintenance
- Weekly, cleanse the valve surface; check air hose connections for any leaks.
- Conduct a monthly evaluation of response time and meticulously log the data.
5.2 Periodic Service
- Every six months, renew seals; clean the spool meticulously with anhydrous ethanol.
- Conduct annual expert calibration of solenoids and sensors to maintain precision.
6. Troubleshooting
Symptom Possible Cause Solution
Valve Inaction Power off / Coil burnout Inspect wiring; substitute the coil if necessary
Air Leakage: Experience seal degradation or loose fittings causing inefficiencies? Ensure optimal performance by replacing the seals or tightening the fittings.
Delayed Response: Facing low pressure or a spool blockage? Elevate your system's responsiveness by increasing pressure or meticulously cleaning the spool.
7. Safety Warnings
- 1. NEVER attempt to disassemble the valve while under pressure! Always ensure the system is fully depressurized before any servicing activities.
- 2. Internal adjustments are strictly prohibited unless performed by authorized experts.
- 3. If you encounter abnormal noises or leakage, initiate an immediate shutdown to prevent further damage.
